Define a class like this:

internal static class NativeMethods
 {

     // Import SetThreadExecutionState Win32 API and necessary flags

     [DllImport("kernel32.dll")]

     public static extern uint SetThreadExecutionState(uint esFlags);

     public const uint ES_CONTINUOUS = 0x80000000;

     public const uint ES_SYSTEM_REQUIRED = 0x00000001;

 }

Put this to the main method: (make sure its before application.run call)

// Set new state to prevent system sleep. (Note: still allows screen saver)

var previousExecutionState = NativeMethods.SetThreadExecutionState(NativeMethods.ES_CONTINUOUS | NativeMethods.ES_SYSTEM_REQUIRED);
